Customize the widget

The widget reads its look and words from your workspace settings each time it loads. Change them in Inbox → Settings and every installed widget updates, with no deploy on your side.

What you can change#

Setting	Where it shows	Default
Brand name	Top of the widget, and the header of emails Relay sends.	Acme
Accent color	Widget header, launcher, buttons and links; the feedback board; email headers.	#4F46E5
Greeting	The large welcome line on the widget’s home screen.	Hi there 👋 How can we help?
Agent name	How your replies are signed, in the widget and on the feedback board.	Alex from Acme

Settings has a live preview of the widget, so you can see changes before you save.

Choosing an accent color#

White text sits on the accent color, so pick a color dark enough for white text to stay readable (roughly 4.5:1 contrast).
Use your product’s primary brand color so the widget feels built in.
Any hex value works. The swatches in Settings are safe starting points.

Writing a greeting#

Keep it short and set expectations. For example: “Hi there 👋 Ask anything, we usually reply within a few hours.” When a signed-in user opens the widget, the “Hi there 👋” part is replaced with their first name.

Want a completely different look?

The widget’s layout is fixed so it stays accessible and consistent. If you need full design control, the feedback board has a headless API. For support chat, the Widget API is documented too, but building your own chat UI is a larger project.
